Description

The ST95HF is an integrated transceiver IC for contactless applications. The ST95HF manages frame coding and decoding in Reader and Card Emulation modes for standard applications such as Near Field Communication (NFC), proximity and vicinity standards. The ST95HF embeds an Analog Front End to provide the 13.56 MHz Air Interface. The ST95HF supports ISO/IEC 14443 Type A and B communication in Reader and Card Emulation modes, ISO/IEC 15693 (single or double subcarrier in Reader mode only) and ISO/IEC 18092 communication protocols in Reader and Card Emulation modes. The ST95HF also supports the detection, reading and writing of NFC Forum Type 1, 2, 3 and 4 tags.
